MAMMALIAN ORGAN SYSTEMS
In this, our final lab of the semester, we will review the major structures and corresponding
functions of the organ systems that we have studied. This will include components of the
following systems:
1)
2)
3)
4)
Nervous
Endocrine
Integument
Skeletal
5)
6)
7)
8)
Muscular
Cardiovascular
Lymphatic
Respiratory
9) Digestive
10) Urinary
11) Reproductive
To facilitate this process, we will make use of both models and dissection procedures.
I. HUMAN ORGAN SYSTEMS
Using the human torso model, identify the organs listed below by model number, the body system
(or systems) they are part of and their primary functions. This will help you familiarize yourself
with the components of these organ systems prior to identifying the "real" organs in the
dissection exercise.

II. FETAL PIG DISSECTION
Based on the identification and orientation activities associated with the previous exercise, we
will now use preserved mammals (fetal pigs) to observe a more “true to life” association of these
organs and tissues within the body. Use the handout provided and the directions given to begin
the dissection. Once you locate the organs indicated below, your instructor will sign off for
confirmation.
A. Organs of the Abdominopelvic Cavity
1. Digestive System
_____ stomach
_____ small intestine
_____ duodenum
B. Organs of the Thoracic Cavity
1. Circulatory System
_____ heart
_____ left atrium
_____ left ventricle
_____ large intestine (spiral colon)
_____ right atrium
_____ liver
_____ right ventricle
_____ gallbladder
2. Urinary System
_____ kidneys
_____ ureters
_____ urinary bladder
_____ aorta
_____ pulmonary artery
_____ vena cava
2. Respiratory System
_____ larynx*
3. Lymphatic System
_____ spleen
_____ trachea*
4. Endocrine System
_____ adrenal glands
_____ diaphragm
_____ pancreas
5. Reproductive System
_____ testes / ovaries
BIO 102 – Mammalian Organ Systems
_____ lungs
3. Endocrine System
_____ thyroid gland*
*associated with or located near the
thoracic cavity
